An arrangement (22) counts the clock signals and delivers timing signals. These timing signals define horizontal scanning display period, horizontal scanning retrace period, vertical scanning display period and vertical retrace period. An arrangement (23) controls the read-out of data to be displayed in accordance with the timing signals and supplies the data to the TV receiver.

Title: Current-type gto inverter
Inventor: MATSUSE KOHOKI
IPC: H02P27/06
Filed: 1984-03-10
Granted: 1989-09-06
Abstract: In the inverter, commutation surge voltage is inevitably generated from an inductive load whenever each GTO is turned off. The commutation surge voltage thus generated is once stored in a capacitor through a diode surge voltage rectifier and then restored or regenerated to the DC source terminals of the GTO bridge-connected inverter through a pair of other GTO turned on only when the capacitor voltage exceeds a predetermined value beyond the DC source voltage.  After energy restoration, magnetic energy stored in a reactor is recharged in the same capacitor.

Abstract: For a pair of complementary input signals which are symmetrically transient, the transistors in a NAND circuit are turned on as are transistors in a second NAND circuit.  At the same time other transistors of the two circuits are turnd off for input signals of high and low levels, respectively.  The output signal of the first NAND circuit is then low level whilst that of the second NAND circuit is high level.  A third NAND circuit, in response to the output signals turns off two transistors and turns on other pair of transistors.  In the three circuits, the transistors are P-channel enhancement MOS transistors whilst the remaining transistors are N- channel enhancement MOS types.

Title: Teletext data extractive circuit
Inventor: JIN JO-CHUL
IPC: H04N7/08
Filed: 1985-05-25
Granted: 1988-04-09
Abstract: The teletext data sampling circuit separates the digital signal from the teletext signal which is mixed in an image signal. When an image input is applied to the data sampling circuit, the average value of Clock Rum-In(CRI) signal only is sampled during the period of Clock Rum-In Window (CRIW) through an input buffer (1) and a low pass filter (2).  The teletext data is obtained by comparing it with the sampling voltage, and the image signal through the buffer and CRI signal only is sampeld by comparing it with the reference voltage and the image signal through band pass filter (3).  So, the circuit can change the teletext signal into parallel data.

Title: Method and apparatus for drawing fiber optic coupler
Inventor: KECK DONALD B
IPC: C03B37/028
Filed: 1986-08-14
Granted: 1991-10-31
Abstract: A low loss fiber optic coupler is fabricated by forming a coupler preform (21) having a plurality of spaced glass cores (26, 27; 26', 27') extending longitudinally through a matrix of glass (21) having a refractive index lower than that of the cores. The coupler preform is heated and stretched by first pulling means (40, 76) to form a glass rod which is drawn by second pulling means (46, 77) past an intermittant source of localized heat (451. When the localized heat source is turned on, the second pulling means (46, 77) draws the rod downwardly at a rate faster than the first pulling means (40, 76). Since the rod is softened by the localized heat source, a necked-down coupling region (51) is formed. The rod is severed to form a plurality of coupler units (81, 87). When an end of a unit is immersed in acid, the matrix glass dissolves, thereby leaving the unit cores and surrounding etch-resistant cladding glass protruding from the newly formed endface of the unit.

Title: Method for processing diamond particles
Inventor: BORSE DIETRICH
IPC: C09C1/68
Filed: 1987-07-30
Granted: 1996-02-16
Abstract: For the use of diamond particles as a component part of machining tools or other tools, it is customary to hold the diamond particles in a bond, in particular a metallic bond. Retention is increased in this case if the diamond particles have a roughened surface. This can take place by etching. In the case of the known methods for processing the surface of the diamonds, they are, however, partially destroyed if processing takes place at high temperatures, that is to say in excess of 1000 DEG C, or there is a great loss of diamond material. This is overcome if, to increase their surface area to at least twice the size of their natural surface area by making pores in them, the diamond particles (1) are embedded in a metal powder and subjected to a stream of hydrogen or a hydrogen-containing gas at a temperature above 700 DEG C. Thereafter, the diamond particles (1) can be cleaned with an acid. Iron, cobalt, nickel or an alloy of these metals come into consideration as metal powder.

Title: Method and system for tinting contact lenses
Inventor: STERMAN SAUL
IPC: B41M1/30

Granted: 1996-06-28
Abstract: A method of tinting soft contact lenses (L) uses at least one transfer-pad printer (2) including a suitable ink of the desired tint, and at least one printing block (6) carrying an iris pattern. The contact lenses are attached to lens mounts (14), preferably by being shrunk onto curved heads (18) of the mounts, and are then aligned, in turn, with the pad (4) of the transfer-pad printer (2). For each lens, the printing block (6) is inked, the pad is caused to pick up the iris pattern from the inked block, and the pad is then caused to make contact with the mounted lens, thereby transferring the iris pattern as picked up from the block to the mounted contact lens. Apparatus for carrying out the method is also described.

<??>Such apparatuses are equipped with a focus control circuit, in order to focus the light beam picking up the data onto the recording medium, and with a tracking control circuit, in order to be able to guide the light beam on the data tracks. The light beam is reflected from the recording medium onto a photodetector (PD) comprising a plurality of photodiodes (E, F). Because actual photodiodes (E, F) are not completely identical, they give off different photoelectric voltages under the same illumination. Therefore, the control amplifier (TR) of the tracking control circuit operates unsymmetrically.
